While on-screen advertising during the Super Bowl is highly desirable, agencies are looking to cash in on outdoor advertisements during the Big Game as well.

All of Clear Channel Outdoor’s billboards on I-95 near MetLife Stadium in East Rutherford are up for grabs, according to a report from the NY Post.

However, according to a report from The Star-Ledger, selective outdoor signs are "secured" for exclusive use by National Football League advertisers.

But that's not stopping ad agencies for selling what some are referring to as "guerrilla advertising," ad campaigns aimed at non-NFL sponsors.

“There are ways to reference [the Super Bowl] without crossing any lines, but you have to be careful,” Matthew Glass of Grand Central Marketing, which is planning an event for Celebrity Cruises during the Super Bowl, told The Post.

CBS Outdoor is offering up ad space in entire New York City subway stations, the Post report said, hoping to take advantage of what the NFL is calling the first “mass transit Super Bowl.” Because of MetLife’s surroundings, the league doesn't plan on many people walking to the game.

Ad spaces in major transportation hubs, like Newark Liberty International Airport, are also being pitched, the report said.

The NFL estimates that the metropolitan area economy will see a boost of as much as $600 million, the report said. This is the first time the Super Bowl is being played in the country’s No. 1 media market.

“We’re seeing pricing premiums here for all media,” Suzanne Grimes, president of Clear Channel Outdoor, North America, told The Post. “Outdoor is un-skippable. There’s no ability to fast forward.”
